EDIT. The title would better be:
When your well designed Revlimiter gauges help save you from disaster.
Apologies for the confusion the title may/has created. Mea culpa.
I love my rally style gauges. Simple layout. Needle in red means trouble ahead. Today the temperature needle dipped red a couple blocks from home. The cursed plug sprung a leak. Ugh. Would I have noticed quickly with a regular gauge maybe, but sometimes the design makes all the difference.
